190-00228-20 GPS 16/17 Technical Specifications Rev. CPage 31.4 OverviewThe GPS 16/17 series products are complete GPS sensors including embedded receiver and antenna,designed for a broad spectrum of OEM (Original Equipment Manufacture) system applications. Based onthe proven technology found in other Garmin 12-channel GPS receivers, the GPS 16/17 tracks up to 12satellites at a time while providing fast time-to-first-fix, one-second navigation updates, and low powerconsumption. This generation of GPS sensors adds the capability of FAA Wide Area Augmentation System(WAAS) differential GPS. The GPS 16/17’s far-reaching capability meets the sensitivity requirements ofland navigation as well as the dynamics requirements of high-performance aircraft.The GPS 16/17 design uses the latest technology and high-level circuit integration to achieve superiorperformance while minimizing space and power requirements. All critical components of the systemincluding the RF/IF receiver hardware and the digital baseband are designed and manufactured by Garminto ensure the quality and capability of the GPS. The hardware capability combined with softwareintelligence makes the GPS 16/17 easy to integrate and use.The GPS 16/17 series products are designed to withstand rugged operating conditions and are waterproof toIEC 60529 IPX7, immersion in 1 meter of water for 30 minutes. These complete GPS receivers requireminimal additional components to be supplied by an OEM or system integrator. A minimum system mustprovide the GPS with a source of power and a clear view of the GPS satellites. The system maycommunicate with the GPS via two full-duplex communication channels. Internal FLASH memory allowsthe GPS to retain critical data such as satellite orbital parameters, last-known position, date and time. Enduser interfaces such as keyboards and displays are the responsibility of the application designer.Note: Due to parts availability, the GPS 17N has been replaced by the GPS 17HVS. References to the GPS17N are for current GPS 17N product information.Note: The GPS 16A has been discontinued. References to the GPS 16A are for current GPS 16A productinformation. A comparable replacement sensor is the GPS 18-5Hz.1.5 Features• 12-channel GPS receiver tracks and uses up to 12 satellites for fast, accurate positioning and lowpower consumption.• Differential DGPS capability using real-time WAAS or RTCM corrections yielding 3 to 5 meterposition accuracy (see Section 1.7 Technical Specifications).• Compact, rugged design ideal for applications with minimal space.• May be remotely mounted in an out-of-the-way location.• Receiver position information can be displayed directly on a chartplotter or PC.• User initialization is not required. Once the unit is installed and has established a location fix, the unitautomatically produces navigation data.• User-configurable navigation mode (2-dimensional or 3-dimensional fix).• (Not Available on GPS 16A or GPS 17N) Highly accurate one-pulse-per-second (PPS) output forprecise timing measurements. Pulse width is configurable in 20 millisecond increments from 20 ms to980 ms with 1 μs accuracy.• Configurable for binary format carrier phase data output on COM 1 port.• Flexible input voltage levels of 3.3 VDC to 6.0 VDC with over-voltage protection in the GPS 16LVS;6.0 VDC to 40 VDC in the GPS 16HVS and GPS 17HVS; and 8.0 VDC to 40 VDC in theGPS 16A and 17N.• FLASH-based program and non-volatile memory. New software revisions available through Web sitedownload. Non-volatile memory does not require battery backup.• Waterproof design allows continuous exposure to the prevailing weather conditions at most locations.
